The back windshield in my 2001 forerunner just completely exploded outwards while it was parked. Observers say nothing hit it, it just totally seemed to explode outwards completely into tiny shreads. Has anyone heard of this? Was there a recall I missed? We live in a very hot climate, but recently it has been fairly mild, so I don't think it was todays heat. Considering how costly the tinted, movable, defogger glass will be, should I contact Toyota?
